FIX: Error message when you use SQL Server Service Broker in SQL Server 2005: "Failed Virtual Allocate Bytes: FAIL_VIRTUAL_RESERVE 589824"

Consider the following scenario.

• In Microsoft SQL Server 2005, you have an application that uses the SQL Server Service Broker.
• In the Service Broker conversation, you create a dialog by using a certificate authentication for transport security.
• The initiator sends a message to the target periodically.
• The time interval between the sent messages is longer than the connection time-out value that is configured for the Service Broker conversation.

In this scenario, after some time, you may find the server runs out of memory. And, you receive the following error message:

This problem occurs because a memory leak occurs when the Service Broker establishes a connection. The memory leak may occur if certificate based authentication is used for a Service Broker dialog. The Service Broker dialog closes when the connection times out. When a later message is sent to the conversation target, the memory leak occurs again. Therefore, after some time, the server runs out of memory.
